Voici un asco sur tige pourrie de jonc à tépales aigus (Juncus acutiflorus) trouvé en pessière-boulaie tourbeuse à sphaignes.
a) asques IKI+, probablement à crochet à la base
b) spores fusiformes à cylindriques-fusiformes, souvent arquées, à microguttules, uniseptées à maturité : 9-13x2,5

Re : Asco sur tige pourrie de Juncus acutiflorus
No idea. The excipulum would be important. Paraphyses and their contents? No hairs?

Re : Asco sur tige pourrie de Juncus acutiflorus
I'll check paraphyses, excipulum and hairs this afternoon. Thank you Zotto.

Re : Asco sur tige pourrie de Juncus acutiflorus
Couldn't it be a Mollisia? There are several on Juncus.
Paraphyses would be important, indeed.

This must be a Hyaloscypha.

OK Zotto, thank you!
I imagine since it's hard to go further ...

Re : Asco sur tige pourrie de Juncus acutiflorus
hello,
Hyaloscypha fuckelii var fuckelii (Crozier+) is reported from Juncus stems. Even the sporesize might fit (measures in monograph are of dead spores). H. secalina might work, but it has narrower spores. Just ideas, no hard evidence.
Surely there are many things on Juncus... unreported.
